Free alternatives to Koalendar
Koalendar keeps things simple, and for a lot of people the free plan is enough. The limits are specific though. You get two calendar syncs and Google Meet only (as of July 2026), so a work plus personal plus shared team calendar already puts you over, and Zoom or Teams users are paying by definition. Payments, SMS reminders, round-robin and group sessions are all Pro at $6.99 per seat, and Koalendar counts a bookable room as a seat, so a studio with four rooms pays for four. If you have hit one of those walls, here is where to go.

Best Free Alternative ToKoalendarUnlimited calendars and free payments where Koalendar caps both
Cal.com removes the exact caps that push people off Koalendar's free plan. It connects unlimited calendars for free where Koalendar allows two, and it includes Stripe and PayPal payments at no cost where Koalendar makes them a Pro feature (as of July 2026). You also get Zoom, Teams, and 100+ integrations rather than Google Meet alone. The cost is a denser interface, so the five-minute setup is gone.
- Free plan, paid from $12/month (as of July 2026)
- United States
- Open source (AGPL-3.0 (core), commercial license for the /ee enterprise directory)
United States- Best for:
- Koalendar users who hit the two-calendar cap or wanted to charge for bookings free
- The catch:
- The free plan is single-user and the interface has more surface area, so team features need $12 per user and setup takes longer.
Compared to Koalendar
- Advantage: Unlimited calendar connections free, versus Koalendar's two
- Advantage: Stripe and PayPal payments included free, which Koalendar makes a Pro feature
- Advantage: Zoom, Teams and 100+ integrations, not just Google Meet
- Advantage: Unlimited event types, matching Koalendar's unlimited free bookings
- Tradeoff: Denser interface, so the five-minute setup is gone
- Tradeoff: Team features need $12 per user, above Koalendar's $6.99 per seat
Unlimited free calendars and links, still simple
Zcal is the pick if you liked how light Koalendar felt but ran into its two-calendar limit. The free plan connects unlimited calendars and unlimited scheduling links (as of July 2026), adds meeting polls, and puts real care into how the booking page looks, while staying simpler than Cal.com or Calendly. If you charge for bookings, note the 3% platform fee, where Koalendar's free plan simply has no payments.
- Free plan (as of July 2026)
- United States
- Best for:
- People who wanted Koalendar's simplicity but needed more than two calendars
- The catch:
- The 3% fee applies to paid bookings on the free plan, and team features sit on the paid Business plan.
Compared to Koalendar
- Advantage: Unlimited connected calendars free, versus Koalendar's two
- Advantage: Meeting polls built into the free plan
- Advantage: Booking pages look more designed
- Advantage: Still simpler to set up than Cal.com or Calendly
- Tradeoff: 3% fee on paid bookings, where Koalendar's free plan has no payments at all
- Tradeoff: Team features only on the paid Business plan
- Worth knowing: Zcal lists plan prices only on its live pricing page
The deepest integration catalogue and Zoom on the free plan
Calendly is worth a look if the Google-Meet-only limit was your problem and integrations matter. Its free plan includes video options beyond Google Meet, and its catalogue is the largest here. The reason it ranks below the free picks is its own free cap: one event type and one connected calendar (as of July 2026), which is tighter than Koalendar's unlimited bookings.
- Free plan, paid from $10/month (as of July 2026)
- United States
- Best for:
- People who need Zoom on the free plan and lean on a large integration catalogue
- The catch:
- The free plan is one event type and one calendar, and paid seats are $10 to $16 against Koalendar's $6.99.
Compared to Koalendar
- Advantage: Video options beyond Google Meet, including Zoom, on the free plan
- Advantage: Larger integration catalogue and a smoother booking flow
- Tradeoff: Free plan allows one event type and one calendar, tighter than Koalendar's unlimited bookings
- Tradeoff: Paid seats $10 to $16, above Koalendar's $6.99
- Tradeoff: No self-hosting
One $29 payment instead of $6.99 per seat every month
TidyCal fits people whose upgrade path off Koalendar's free plan looked expensive once rooms counted as seats. Its free tier allows unlimited bookings and booking types, and the paid feature set unlocks with a single $29 lifetime purchase on AppSumo (listed against a $144 reference price, as of July 2026). It is cheap rather than free-forever, and a plainer product than the hosted rivals on design.
- Free plan, paid from $29 one-time (as of July 2026)
- United States
- Best for:
- Small operators who would rather buy once than pay per seat every month
- The catch:
- The $29 is an AppSumo promotion rather than a permanent price, and the free tier holds back custom domains, SMS and most integrations.
Compared to Koalendar
- Advantage: $29 one-time unlock instead of Koalendar's $6.99 per seat every month
- Advantage: Free tier allows unlimited bookings and booking types
- Advantage: Agency lifetime at $79 covers multiple booking accounts
- Tradeoff: Free tier holds back custom domains, SMS and most integrations
- Tradeoff: Interface is functional rather than polished
- Worth knowing: Lifetime pricing lives on AppSumo, so availability can change
No per-seat bill for a multi-room business
Easy!Appointments is the answer to Koalendar's per-seat trap for a studio or clinic. Because you host it, it is free at any number of rooms or staff, where Koalendar charges $6.99 for each bookable resource. It is GPL-3.0, takes no commission, and models services, providers, and working plans natively. Version 1.6.0 shipped in May 2026. The cost is running Apache or Nginx, PHP 8.2, and MySQL yourself.
- Completely free (as of July 2026)
- Greece
- Open source (GPL-3.0)
Greece- Best for:
- Multi-room studios and clinics that can host PHP and want no per-seat bill
- The catch:
- You run the server, updates and backups yourself, and there is no hosted signup path like Koalendar's browser setup.
Compared to Koalendar
- Advantage: Free at any number of rooms or staff, where Koalendar charges per resource
- Advantage: Models services, providers and working plans natively
- Advantage: No commission and no subscription
- Tradeoff: You run PHP 8.2 and MySQL yourself
- Tradeoff: No hosted signup path, unlike Koalendar's browser setup
- Tradeoff: Dated interface
Group date polls, which Koalendar does not do
Rallly covers a job Koalendar does not: finding one date that works across a group. You propose several dates, share a link, and people vote without needing an account. It is free, AGPLv3, and self-hosts from a Docker image, so it pairs with a booking tool rather than replacing Koalendar. Include it only if group availability is part of your problem.
- Free plan, paid from $56/year (as of July 2026)
- Germany
- Open source (AGPL-3.0)
Germany- Best for:
- Groups picking a shared date, alongside a simple booking tool
- The catch:
- Not a 1:1 booking tool, with no payments or availability rules, and hosted free polls are deleted 30 days after their dates pass.
Compared to Koalendar
- Advantage: Free and open source group polling, which Koalendar does not offer
- Advantage: Self-hostable under AGPLv3
- Advantage: Voters need no account
- Tradeoff: Not a 1:1 booking tool, so it cannot replace Koalendar
- Tradeoff: No payments or availability rules
- Tradeoff: Free hosted polls deleted after 30 days of inactivity
How to choose
If you want to keep a free plan but lose the caps, Cal.com is the pick: unlimited calendars, unlimited event types and Stripe payments, all free for one person. Zcal stays nearly as simple while adding unlimited links and a better-looking page. Calendly is the choice if integrations matter more than the free tier, and TidyCal if you would rather pay $29 once than $6.99 per seat every month. Self-hosted Easy!Appointments suits a multi-room business that wants no per-seat bill at all, and Rallly handles the group date polls Koalendar does not.
